Question 224281
y=-2x/3-12


I assume you want to plot the line. It takes two points to plot the point.


Step 1.  Let x=0, then y=-12.  So one point is (0,-12).


Step 2.  Let y=0, then{{{0=-2x/3-12}}} or {{{12=-2x/3}} or {{{x=-18}}}. So the other point is (-18,0)


{{{graph(600,600, -20, 20, -20, 20, -2x/3-12)}}}


Also note that the above line is given as slope-intercept form given as y=mx+b where m is the slope and b is the y-intercept when x=0 or at point (0,b).  For the above example, the slope m=-2/3 and b=-12 or at point (0,-12).


I hope the above steps and explanation were helpful.
